SHUTTLE.

Specification of Letters Patent. Patented Aug. 29, 1911- Applicationfiled September 10, 1910. Serial No. 581,346.

To all whom it may concern:

Be it known that I, EDWARD VVAGKER- HAGEN, a citizen of the UnitedStates, and resident of Fort Lee, in the county of Bergen and State ofNew Jersey, have invented certain new and useful Improvements inShuttles, of which the following is a specification.

The object of my invention is to provide improved means to resist orprevent breaking of the threads as drawn from the bobbins in theshuttles; to maintain proper tension on the threads, and to guide thethreads in their shuttles from the bobbins in an effective manner.

My invent-ion comprises novel details of improvement and combination ofparts that will be more fully hereinafter set forth and then pointed outin the claim.

Reference is to be had to the accompanying drawings forming part hereof,wherein,

Figure 1 is a plan view of a shuttle, partly broken away, embodying myimprovements; Fig. 2 is an edge view thereof; Fig. 3 is a section on theplane of the line 3, 3, in Fig. 1; Fig. 4 is a cross sectionsubstantially on the plane of the line 4, 4;, in Fig. 1; and Fig. 5 is asimilar section substantially 0n the plane of the line 5, 5, in Fig. 1.

Similar numerals of reference indicate corresponding parts in theseveral views.

The shuttle 1 is shown provided'with the pin or stud 2, upon which thebobbin 3 is mounted in suitable manner, said bobbin being shown providedwith an annular recess 3 receiving the spring 4 carried by the shuttle,for retaining the bobbin on pin 2. At 5 are a suitable number of tensionpins carried by the shuttle over which the thread 6 of the bobbinpasses, and at 7 is a movable member, shown in the form of a plate,pivotally supported at one end upon the shuttle, and adapted to swing ona pivot 8, said member 7 having a suitable number of tension eyes 7beneath the pins 5, the thread 6 being shown passing over and under theguides 5 and 7 successively. The relation of the pins and the eyes issuch, that when the plate is swung toward the pins 5, the eyes and pinsintermesh, whereupon, the thread 6 may be passed through the eyes overthe side of the pins farthest from the plate 7 and in a straight line;thus providing a quick and easy means of threading the shuttle. Member 7is adapted normally to rest upon a support, shown in the form of a pinor bar 9, being normally retarded in that position by means of gravity,and the thread is zigzagged over the pins and through the eyes, thusproviding a tensioning means for the thread. The thread 6 passes fromthe guides 5, 7 to an eye 10 carried by a spring 11, shown in the formof a coiled spring received within a borel of shuttle 1 and retained bya pin 12. From the eye 10 thread 6 passes to an eye 13 carried by aspring 14;, which may be arranged similarly to spring 11; from eye 13thread 6 passes to an eye 1O carried by spring 11, and from the eye 10thread 6 passes through the hole or guide 1 of the shuttle. The eyes 10,10 are formed in the respective furcations of the bifurcated memberwhich is connected to one of the travelers 16. By means of thisarrangement, the thread passes rightward and downward through the eye ofthe upper furcation, and afterward passes through the eye of the lowerfurcation 10 and thereby avoids undesirable contact or interference atdifferent sections of the thread, such as would result by passing thethread twice through a single eye. The member 13 is also shown connectedwith one of the travelers or rings 16, which is adapted to travel upon aguide 15, shown in the form of a wire or bar extending along the outerportion df the shuttle, and free between its ends 15 that are attachedto the shuttle, whereby said eyes are movably retained in properposition against the tension of thread 6, and yet said eyes may havefree movement as the thread passes through them. The members 10, 10, 11,13, 14;, 15, and 16 collectively constitute a take up means for thethread, as well as an auxiliary tension therefor.

At 17 is a guide carried by the shuttle and bearing against the cop orspool 3 of the bobbin, between which guide and cop or spool the thread 6passes. Guide 17 is preferably made of fibrous material, such as felt,

or the like to bear with slight tension upon the thread passing betweenthe same and the cop, and yet with suflicient friction to retain thethread against the cop and serve as'a check to prevent surplus unwindingof the thread as it passes to the guides 5, 7

As the thread is drawn from the shuttle, during reciprocations of thelatter, in a loom or other machine, the thread will be held under thedesired tension by the springs 11, 14 and the eyes 10, 10 and 13, whicheyes may have free movement as required, and the member 7, as the threadpasses along the guides 5, 7 will rise and fall as may be required tomaintain tension upon the thread, take up slack in the thread, and tendto prevent undue unwinding of the thread from the bobbin. The threadwill thus be maintained under the tension at all times, during operationof the shuttle, and if at any time extra tension comes uponthe threadthe member 7 will be lifted by the thread to vary the relative positionsof guides 5 and 7 and lessen the resistance to the thread at suchguides.

My invention is not limited to the details of construction set forth, asthe same may be varied, within the scope of the appended i of New Yorkand State of New York this claim, without departing from the spiritthereof.

Having now described my invention what I claim is:

In combination with a shuttle having a 3 thread carrymg means thereln, athread tensionmg device in an end of sald shuttle, an 1 'the oppositeendof the shuttle from said thread tensioning device and comprising abifurcated member havlng eyes in the furcations thereof foraccommodating and separating the oppositely moving portions of thethread, substantially as described and specified.
